Lessons learned from stellar occultations by Trans-Neptunian Objects and prospects for the future

Résumé

The best way to derive physical properties of solar system bodies is to send spacecraft to observe them. Probably the second best means to learn about important physical properties of solar system objects is through stellar occultations. Since October 2009, when the first stellar occultation by a Trans- Neptunian Object other than Pluto was recorded, around seventeen more occultations by Trans- Neptunian Objects have been detected, thanks to the efforts of several teams. Due to the complications of accurately predicting and observing these events, most of the successes have been achieved by an international collaboration of three main teams that coordinate different important aspects, but there have also been other successes in the field. Nevertheless, most of the successes involved large groups of researchers and even amateurs. Here we present a preliminary and brief summary of some of the results obtained thus far as well as a summary on some of the lessons learned to improve the rate of success. A key issue is involving large groups of observers once an accurate prediction has been made.
